Answer:

36 + 3b = 117

Step-by-step explanation:

36 is the one specialized cake he sold.

3 is the cost and b is how many it represents

117 is your total, so we piece it together.

36 + 3(b) = 117

Answer:

Part 5.1.1:

[tex]\displaystyle \cos 2A = \frac{7}{8}[/tex]

Part 5.1.2:

[tex]\displaystyle \cos A = \frac{\sqrt{15}}{4}[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle \sin 2A = \frac{\sqrt{15}}{8}[/tex]

Part 5.1.1

Recall that:

[tex]\displaystyle \sin^2 \theta + \cos^2 \theta = 1[/tex]

Let θ = 2A. Hence:

[tex]\displaystyle \sin ^2 2A + \cos ^2 2A = 1[/tex]

Square the original equation:

[tex]\displaystyle \sin^2 2A = \frac{15}{64}[/tex]

Hence:

[tex]\displaystyle \left(\frac{15}{64}\right) + \cos ^2 2A = 1[/tex]

Subtract:

[tex]\displaystyle \cos ^2 2A = \frac{49}{64}[/tex]

Take the square root of both sides:

[tex]\displaystyle \cos 2A = \pm\sqrt{\frac{49}{64}}[/tex]

Since 0° ≤ 2A ≤ 90°, cos(2A) must be positive. Hence:

[tex]\displaystyle \cos 2A = \frac{7}{8}[/tex]

Part 5.1.2

Recall that:

[tex]\displaystyle \begin{aligned} \cos 2\theta &= \cos^2 \theta - \sin^2 \theta \\ &= 1- 2\sin^2\theta \\ &= 2\cos^2\theta - 1\end{aligned}[/tex]

We can use the third form. Substitute:

[tex]\displaystyle \left(\frac{7}{8}\right) = 2\cos^2 A - 1[/tex]

Solve for cosine:

[tex]\displaystyle \begin{aligned} \frac{15}{8} &= 2\cos^2 A\\ \\ \cos^2 A &= \frac{15}{16} \\ \\ \cos A& = \pm\sqrt{\frac{15}{16}} \\ \\ \Rightarrow \cos A &= \frac{\sqrt{15}}{4}\end{aligned}[/tex]

In conclusion:

[tex]\displaystyle \cos A = \frac{\sqrt{15}}{4}[/tex]

(Note that since 0° ≤ 2A ≤ 90°, 0° ≤ A ≤ 45°. Hence, cos(A) must be positive.)

Step-by-step explanation:

im pretty sure thats the answer

Answer: y=-8

Step-by-step explanation:

If the slope is zero that means that the line does not go up (or have any rise) and therefore must be a horizontal line. Since it passes through the point (3,-8), the equation has to be y=-8.

Answer:

x square + 3 Square

(x + 3)square

X Square + 3 Square + 2x3

Answer:

x = 13

Step-by-step explanation:

A linear pair of angles sum to 180° , then

2x + 9 + 10x + 15 = 180 , that is

12x + 24 = 180 ( subtract 24 from both sides )

12x = 156 ( divide both sides by 12 )

x = 13

Answer:

x = 1

Step-by-step explanation:

Given

1000x = 1000 ( divide both sides by 1000 )

x = [tex]\frac{1000}{1000}[/tex] = 1

The given equation is,

→ 1000x = 1000

Let's find the required value of x,

→ 1000x = 1000

→ x = 1000/1000

→ [x = 1]

Therefore, 1 is the value of x.

Answer:

The following correct answer is c.

This I because when you translate using this, you first start with the point (0,0), translate that point down 3 (-3 means down three when outside parenthesis) and translate it to the right 4 units (this shown in a paraptosis, and when you move to the right you say -4, but if you move to the left you say +4)

Answer:

- [tex]\frac{12}{20}[/tex]

Step-by-step explanation:

To obtain a denominator of 20 requires the numerator and denominator to be multiplied by 4 , that is

- [tex]\frac{3}{5}[/tex] = - [tex]\frac{3(4)}{5(4)}[/tex] = - [tex]\frac{12}{20}[/tex]

The independent variable, x, represents the number of questions Riley answered correctly, and the dependent variable is the score, because the score depends on the number of questions Riley answered correctly. A function relating these variables is R(x) = [3x] So R(23) = [69], meaning 23 correct answers will give a score of 69.

In an experiment, there are two (2) main types of variables and these include:

An independent variable can be defined as the variable that is being manipulated by an experimenter or researcher. This ultimately implies that, it is typically considered to be the cause in an experiment and represented by x.

In this scenario, we can infer and logically deduce that the independent variable, x, represents the number of questions Riley answered correctly, and the dependent variable is the score, because the score depends on the number of questions Riley answered correctly. A function relating these variables is R(x) = [3x] So R(23) = [69], meaning 23 correct answers will give a score of 69.

Answer:

y=1/3x+7

Step-by-step explanation:

1. The given equation is y=1/3x-6 and it has to be parallel passing through (-12,3), so you just plug in the x and y values into the equation y=mx+b with 1/3 as the slope since its parallel (meaning the slope is the same for both eqts)

2. 3=1/3(-12)+b

3. 3=-4+b

4. 7=b

5. So, the equation is y=1/3x+7

Answer:

Its 48 °

Since its a triangle, the total angle will be 180°

So,

x° + 42°+90°=180°(90° as one angle in triangle is 90°)

x°=180°-90°-42°

x°=48°

Answer: 48º c:

Step-by-step explanation:  So basically the angle at the top, lets call it A, is 42º. And the angle at the bottom right, is a right angle, which is 90º. We know this by the square at the angle. If we call this angle B, then through the fact that triangles will always have a combined angle measuremnt of 180º, we can do a + b + x = 180, which will be 42 + 90 = 132, 180 - 132 = 48 :)

Answer:

5)7:8=180

84:96=180

6)4:5=90

40:50=90

7)a). q=135

p=45

b).a=70

b=110

supplementary angle=sum of two angle 180°

complementary angle=sum of two angle 90°

Answer:

The two angle 7 and 8 —> 7x and 8x

Sum of two supplementary angle is 180°

7x +8x =180

15x =180

x= 180/15

x = 12°

7x =7(12)= 84°

8x = 8(12)= 96°

The angles; 84° , 96°

The two angle 4 , 5 —> 4x and 5x

Sum of two complimentary angle is 90°

4x+5x =90

9x =90

x=90/9

x=10

4x—> 4(10) = 40°

5x —> 5(10) = 50°

The angles; 40° , 50°

q= 135 ( Vertically Opposite angles)

q+p = 180

135+p=180

p=180-135

p = 45°

_______o_____o_____

a= 70° ( Alternate angles)

a+ b = 180

70 + b = 180

b =180 - 70

b = 110

So ; angle a=70° , b = 110°
